STENCIL-PRINTING APPARATUS.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application led November 19, 1907. Serial No. 402,806.

To all whom it may concern:

Be it known that I, DAVID GESTETNER, a Subj ect of the King of 1GreatBritain, residing at Tottenham Hale, in the county of MiddleseX,England, have invented new and useful Improvements in and Connected withStencil-Printing Apparatus, of which the following is a specification.

The invention relates to improvementsin and connected with stencil andink carrying frames of the character described in U. S. A. LettersPatent dated th 28th November 1905 N0. 805,536. A

I will describe my invention by the aid of the accompanying drawings, inwhich Figure 1 is a plan view of a complete stencil and ink carryingframe constructed according to my invention, Fig. 2 is a view of the inkpad separately and Fig. 3 is a back view of the stencil and ink carryingframe.

a is the frame, which as shown is made in one piece with the inkproof-backing b, and c is the ink pad over which the stencil (not shown)is placed. Heretofore, the ink pads c on suchv frames a have been madeof porous paper or of a fine fabric, on which a supply of ink has beenspread and over which the stencil is placed. Now when printing from suchframes by rolling pressure as heretofore, the ink is caused by theroller to spread laterally which sometimes results in soiling' theframes and work. According to my present invention I substitute for thesaid porous paper or fine fabric, a sheet of finely and closelyperforated bibulous paper `c and spread the ink over the same. Thisresults in4 some of the ink entering the perforations, by which means ahold is obtained on the general body of ink andthe liability to lateralspreading of the ink is thereby prevented or greatly reduced, while apossible flow of the ink when the frames are stored is prevented orreduced. This construction of ink pad also facilitates printing by meansof direct pressure from a pressure plate instead of by rolling pressure.I also according to my invention mount the ink, pad on a metal or otherbacking which latter and the frame are so formed that the ink pfad withits backing can be readily removed om the frame and another ink adsubstituted for it. For thispurpose t e frame a is formed at each endwith aninclined clip d and on each side with one or more projections e.

The ink pad backing f is formed with inclined ends f so as to enable itto be readily passed under the clips d and against a pro-- jection orprojections e near one side edge of the frame, when the opposite edge ofthe backing f will be held by the projection or projections e near theopposite side edge of the frame. The ink pad c may be connected to thebacking f or it may be held thereon by being assed under the clips f2located upon the 1n pad backing. I also provide the frame with means forholding an indicating cardvto indicate the matter contained on thestencil. For this pur ose I form a clip g along each side ed e o theframe on the oposite side to that olding the ink pad. Under these clipsthe indicating card h is slipped and I form ribs i near each end of theframe to prevent the indicating card slipping endwise. These ribs i alsoact to stiffen the frame.

What I claim is 1. In stencil and ink carrying frames for stencilprinting apparatus, an ink pad of finely and closely perforated bibulouspaper substantially as herein set forth and for the purpose stated;

2. In stencil and ink carrying frames for stencil printing apparatus, anink pad of finely and closely perforated bibulous paper and a removablebacking on which such ink pad is fixed substantially as herein setforth.

3. In stencil and ink carrying frames for stencil printing apparatus, anink pad of finely and closely perforated bibulous aper and a removablebacking on which suc mk pad is xed, a frame to carry the ink pad, endcli s on said frame, studs near each side edge o the frame and inclinedends to the ink pad backing-.substantially as herein set forth.

4. In stencil and ink carrying frames for stencil rinting, a frame,having on its front means or holding an ink pad and stencil and on itsback, clips along each side edge and ribs near each end to hold anindicating card substantially as herein set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

DAVID GESTETNER.
